  • this conductive adhesive 120 provides an electrical contact between the bumps 110.1, 110.2 of the chip 100 and the ends 12.1, 12.2 of the antenna conductor without, however, establish electrical contact between the terminals with each other and between the bumps of the chip with each other.
  • the transponder chip 100 has, inter alia, a processor suitable for contactless data transmission and an electronic memory.
  • the antenna structure 12 and the transponder chip 100 fixed and electrically contacted on the antenna structure together form an electrical circuit 1, here a transponder unit, which is arranged on the carrier foil layer 10.
  • the compensation film layer 20 has an opening 22 which is located at the location where the chip 100 is also located on the carrier film layer 10.
  • the aperture 22 further has the shape of the chip 100 and is about as large as this.
  • the compensating film layer 20 has approximately the thickness of the mounting of the chip 100 corresponding thickness, so that the top of the chip after placing the compensation film layer 20 on the carrier film layer 10 with the top of the compensation film layer forms a substantially flush surface. The chip 100 therefore fills the aperture 22 approximately completely.
  • the carrier foil layer 10 and the compensating foil layer 20 can also first be gathered together and the transponder chip 100 can then be mounted in the opening 22.
  • the final film layer 30 is placed, which closes the stack of carrier film layer 10 and compensating film layer 20 upwards and thus also closes the opening 22 ( Fig. 1d ).
  • the closure film layer 30 is also preferably made of PC.
  • the polymer material of the cover film 30 may be the same as that of the compensating film layer 20. Therefore, its glass transition temperature T g, DF is just as large, namely about 150 ° C, as that of the compensating film layer 30.
  • the final film layer 30 may be opaque white by fillers, so that the Transponder chip 100 and the antenna structure 12 are no longer visible from the outside.
  • a cover film layer 40, 50 are placed on the two outer sides of the thus formed film stack of carrier film layer 10, leveling film layer 20 and closing film layer 30, which are transparent and can reveal underlying structures ( Fig. 1d ).
  • the Cover film layers 40, 50 are preferably made of PC.
  • the polymer material of the cover film layers 40, 50 may be the same as that of the compensating film layer 20 and the final film layer 30. Therefore, its glass transition temperature T g, DF is the same, namely about 150 ° C, as those of these film layers.
  • the closure sheet 30 may be printed with a photograph of the owner of the document 200 (in FIG Fig. 1d not yet finished, not yet laminated), which can be seen through the overlying transparent cover film layer 50.
  • FIG Fig. 2 A section along III-III through the stack 70 of the document 200 is shown in FIG Fig. 2 shown.
  • Recognizable are the carrier film layer 10 with the antenna structure 12 applied thereon with the connection contacts 12.1, 12.2 and the transponder chip 100 contacted thereon. This has contact bumps 110.1, 110.2 which rest on the connection contacts 12.1, 12.2.
  • the chip 100 is mechanically and electrically mounted on the carrier film layer 10 by means of an anisotropic conductive adhesive 120.
  • the compensation film layer 20 can be seen with the opening 22 into which the chip 100 protrudes.
  • On the compensating film layer 20 is the final film layer 30. This stack is completed by the two other transparent cover film layers 40, 50 on both sides.
  • the film layers 10, 20, 30, 40, 50 together form the film layer stack 70.
  • the stack is laminated, ie laminated together in a laminating press, for example a continuous laminating press, under elevated pressure and under the influence of elevated temperature.
  • a laminating press for example a continuous laminating press
  • the stack is exposed in a hot press to a laminating temperature T L of 180 to 190 ° C and a pressure of 350 N / cm 2 and in a cooling press at a pressure of 600 N / cm 2 .
  • the laminating temperature T L is significantly higher than T g, DF , but lower than T g, TF , the polymer materials flow to the compensating film layer 20, the final film layer 30 and the cover film layers 40, 50 but not the polymeric material of the backing film layer 10 the transponder chip 100 stabilizes on the antenna structure 12, so that the contacting of the chip during lamination is not impaired.
  • the lamination creates a monolithic composite that yields the document 200.
  • the document 200 may be equipped with other security features.
